"We Belong Together" is a song by American singer-songwriter Mariah Carey from her tenth studio album, The Emancipation of Mimi (2005). The song was released on March 29, 2005, through Island Records as the second single from the album. "We Belong Together" was written by Carey, Jermaine Dupri, Manuel Seal, and Johntá Austin, and produced by the former three. As the song samples lyrics from Bobby Womack's "If You Think You're Lonely Now" (1981) and The Deele's "Two Occasions" (1987), several others are credited as songwriters. Following the release of "It's Like That", the album's lead single, which features a strong beat and production, "We Belong Together" is built on a simple piano arrangement with an understated backbeat. According to Carey, this was done to highlight her vocals, instead of having them obscured by heavy instrumentation. The song's lyrics chronicle a woman's desperation for her former lover to return after their separation and her loneliness following his departure.
